American Pacific Mining Corp. Reports Phase I Drill Results

The Phase I drill program included 15 holes of combined core and reverse circulation ("RC") drilling totaling 4,581 metres ("m"). Highlights from the program include:

• A new vein identified by drill hole GB21-09, 35 m from the known mineralization, indicating the potential for a multi-vein system running parallel to the historic high-grade Gooseberry vein.

• GB21-09 cut 17.5 m of 95.5 grams per tonne ("g/t") silver ("Ag") and 0.94 g/t gold ("Au"); including 4.6 m of 313 g/t Ag and 2.98 g/t Au (547 g/t silver equivalent¹).
• Very limited drilling over approximately 1500 metre target trend to the west southwest of new zone; geochemical program planned to refine targets for Phase II step-out drilling.

"Our Phase I drill program was focused on identifying new zones of mineralization at our Gooseberry Project and we believe we have succeeded," stated American Pacific President Eric Saderholm. "We believe this newly discovered zone represents at least one parallel vein set and possible mineralized crossing features that were never identified during previous mining which terminated in 1991. This vein and structural system are along the same trend and in the same host rocks with apparently the same depositional timing and similar mineralogy as the storied Comstock Lode, which produced 192 million ounces of silver and 8.3 million ounces of gold² during the mid-1800s. American Pacific is now conducting an aggressive geochemical program to help further define this newly discovered mineralization and identify additional targets to the west. A Phase II drilling program will be based upon the results of this work."³

Zachery Hibdon, American Pacific Chief Geologist stated: "At the GB east target zone (Figure 1) we noted a consistent and mappable structural zone highlighted by a breccia with andesite clasts in a clay gouge matrix (Image 1). This zone always preceded a zone of increased silicification, oxidation and veining in the andesite country rock that transitioned to heavily veined zones hosting our higher-grade mineralization. These 2021 intercepts are located a significant distance from the old mine workings highlighted in the Figure 2 plan map. It appears we are in a parallel vein system to the historic Gooseberry vein. This first phase of drilling along with a comprehensive 2022 soil, rock-chip, and mapping program targeted for spring 2022 will provide us data from which to define new drill targets for Phase II drilling later this year."

Phase II Exploration Program Underway

The Company has begun a sampling program of roughly 3000 soil samples as part of the target refinement work in advance of Phase II drilling. The goal of this sampling is to identify the GB vein analog targets to west target area. Once completed and modeled in a 3D space the Company expects to commence a second drill campaign.

The Company also announces that it has granted 2,900,000 incentive stock options (the "Options") to certain directors, officers and consultants in accordance with its stock option plan. The Options are exercisable at $1.01 for a period of 5 years from the date of grant.
